how many times a week should i work out my abs? i do various excerises, and the next day, my muscles ache in that area so i'm not too thrilled about doing anything. but the day after, i'll do the same routine, and the next day, feel no soreness (as though i hadn't done any work).
is it like every second day? three times a week?
don't know.
i know weighttraining, you've to give your muscles a day off or so.
some advice would sorely be welcomed (pun intended)
